General Anaesthesia & Deep Sedation
Whether the clinic documents treatment under general anaesthesia or deep / twilight sedation — "sleep dentistry", where the patient is asleep and unaware (does not feel, see, or hear the procedure). Ordinary conscious sedation, where the patient stays awake and responsive, does not count here. This is informational and does not affect the transparency score.
- ? General anaesthesia / deep sedation (sleep dentistry) — Not verified No sedation/GA info found on own website (dralter.co.za); only a patient testimonial mentions local anesthetic.

Change History
| Date | Change |
|---|---|
| 2026-10-05 | Re-read on 2026-10-05: the practice's former website address, dralter.co.za, still shows a hosting platform's "no page is linked to this domain" notice and its Google listing gives no website, so the link is removed and the English version, structured data and service pages are recorded as absent. |
| 2026-10-01 | Other review platforms re-checked on 2026-10-01: no profile on WhatClinic, Hellopeter or Trustpilot; onOtherPlatforms set to false. |
| 2026-09-30 | Corrected 2026-09-30: published prices and the cleaning, filling, crown, implant, consultation and X-ray prices now unverified: they were read on the practice's former website, which is no longer online, and the practice has no Facebook page. |
| 2026-09-29 | Looked for the dentist and the practice on Facebook by name: no page exists. Recorded: not present on Facebook. |
| 2026-09-24 | Search visibility checked on 2026-09-24 for the five pending Johannesburg queries — "best dentist Johannesburg", "English speaking dentist Johannesburg", "dental implants Johannesburg", "emergency dentist Johannesburg" and "Johannesburg dental clinic for expats": not present for "best dentist Johannesburg", "English speaking dentist Johannesburg", "dental implants Johannesburg", "emergency dentist Johannesburg" and "Johannesburg dental clinic for expats". |
| 2026-09-24 | Re-read on 2026-09-24: the clinic's Google listing (the website at dralter.co.za no longer loads - it now returns a 404 page). Corrected: the website is currently down, so it is no longer counted as an official website; current Google Business Profile hours show no weekend or evening opening. Recorded: genuine staff photos on the Google listing; consistent owner replies including recent ones; two reviews describing undisclosed fees; no signs of manipulated reviews; an archived copy of the former site (dated 2026-02-12, disclosed as such) documents a tooth extraction performed at the practice. Still unverified: TripAdvisor and Facebook presence, X-ray/CBCT equipment, emergency care and work with foreign patients, none of which could be confirmed once the website went offline. |
| 2026-08-25 | License verification 2026-08-25 against HPCSA iRegister: the sole matching registration for Dr. Avron Alter (DP 0028371, Abraham Judah Avron Alter) shows Status SUSPENDED — recorded as verified false per policy on lapsed/suspended registrations. |
| 2026-08-25 | Re-verification 2026-08-25: confirmed website, address, phone unchanged and clinic open; captured first Google rating 4.9 (58 reviews, latest review ~9 months ago). |
